FILL 2 DELAY - The value set on the fill 2 delay is
the amount of time that fill system number two runs
after grain reaches the drying chamber high level rotary
switch. This delay is not used in units with only one
fill system controlled by the Autoflow. The fill 2 delay
should be set long enough so that the drying chamber
high level rotary switch is covered with enough grain
that the fill systems do not start and stop frequently in
the dry cycle due to settling or shrinkage; but, the fill 2
delay should be set short enough so that grain does not
reach the drying chamber overflow rotary switch. The
fill 2 delay is set using the same procedure as the dry
and unload timers, but the reset button does not need to
be pressed to enter the new values into memory
immediately.
OUT OF GRAIN DELAY - The value set on
the out of grain delay acts as a buffer to allow grain
to fall away from the drying chamber low level rotary
switch after the drying fans start without giving an
error. When grain reaches the drying chamber low
level rotary switch the drying cycle starts (if the fan
switch is placed in the “auto” or “on” position) and the
out of grain delay begins to time down. If grain falls
away from the drying chamber low level rotary switch
before the time on the out of grain reaches zero no
error is given and the dryer continues in the drying
cycle. If grain falls away from the drying chamber low
level rotary switch after the out of grain delay reaches
zero a drying chamber no grain error is given and the
dryer shuts down. The out of grain delay should be set
long enough so that the fill system(s) have sufficient
time to make up the grain that falls away from the
drying chamber low level rotary switch when the fan(s)
and heater(s) start; but, should not be set too long. If
the linear actuator fails to retract the dump chutes and
grain runs directly from the drying chamber to the
storage chamber without being dried, the grain would
fall away from the drying chamber low level rotary
switch and a drying chamber no grain error would be
given. If the out of grain delay is set too long and the
linear actuator failed to retract, an unacceptable
amount of wet grain could flow from the drying
chamber to the storage chamber before a drying

chamber no grain error is given and the dryer shuts
down. The out of grain delay is set using the same
procedure as the dry and unload timers, but the reset
button does not need to be pressed to enter the new
values into memory immediately.
FAN DELAY - The fan delay is the delay in
seconds between the starting of the master fan unit and
the slave fan unit. In systems with 220v1ph electrical
power the fan delay should be set at small value - less
than 3 seconds. If the fan delay is set too long the
slave fan could rotate fast enough backwards to start in
a reverse rotation. Use the increase and decrease
buttons to select the fan delay. Press the enter button
when the correct fan delay is displayed to continue to
the main drying screen. In single fan units the fan
delay is not applicable.
FANS OFF DELAY - The fans off delay
allows the fan and heater unit(s) to be shut down
during the dump cycle. This will prevent the drying
floor from becoming excessively dirty when there is a
large amount of foreign material present in the grain
being dried. There are two values that the fans off
delay can be set at presently: 1:00 and 0:00. Use the
increase and decrease buttons to select the value.
When set at 1:00 the fan and heater units will shut off
during the dump cycle. When
CONTROL SYSTEM set
at 0:00 the fan and heater unit(s) will not shut off and
the unit will operate normally.
Set-up : Standard
CLEAR TOTAL BATCHES - Press the reset
button to clear the total batches. Press the enter button
to continue.
CLEAR WARNING HISTORY - Press the
reset button to clear the warning history. Press the
enter button to continue.
TINE UNTIL LOAD OFF - In Autobatch
mode is the percentage of time through the dry cycle
that the fill systems will be shut off regardless if the
dryer is full or not. Press the enter button to return to
the main drying
screen.
